Description

Information transmission method, device and equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on August 11, 2023, with application number 202311012517.8 and application name “A method, device and apparatus for information transmission”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to an information transmission method, apparatus, and device. Background Art

[0003] In related technologies, information transmission schemes for reporting aperiodic channel state information (CSI) typically require a base station to send downlink control information (DCI) to trigger user equipment (UE) to provide feedback. Specifically, if the measurement target is an aperiodic reference signal, the UE will always measure the aperiodic reference signal after receiving the DCI and then report it. This results in a less flexible scheme and may result in unnecessary aperiodic reference signal transmission and / or measurement, thereby causing resource waste and other problems.

[0156] Figure 1 shows a block diagram of a wireless communication system to which embodiments of the present disclosure may be applied. The wireless communication system includes a terminal device (also referred to as a terminal) and a network device.

[0157] The terminal devices involved in the embodiments of the present disclosure may be devices that provide voice and / or data connectivity to users, handheld devices with wireless connection capabilities, or other processing devices connected to wireless modems. In different systems, the names of terminal devices may also be different. For example, in a 5G system, the terminal device may be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CN) via a radio access network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices. For example, they can be portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network.

In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0159] Network devices and terminal devices can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be two-dimensional MIMO (2D-MIMO), three-dimensional MIMO (3D-MIMO), full-dimensional MIMO (FD-MIMO), or massive MIMO. It can also use diversity transmission, precoding, or beamforming.

[0160] The following first introduces the contents involved in the solution provided by the embodiment of the present disclosure.

[0161] In the New Radio (NR) system, in order to combat the path loss in high-frequency scenarios, the transmitter and receiver obtain matching beam pairs through beam management (BM) to improve the beamforming gain. Specifically, in the current downlink beam management process, the base station selects a suitable transmit beam (Tx beam) for subsequent communication based on the beam measurement information reported by the user equipment (UE), and indicates the selected beam information to the UE. However, in this solution, in order to obtain the optimal beam pair, the base station needs to send the Channel State Information Reference Signal (CSI-RS) and / or Synchronization Signal Block (SSB) on all Tx beams, which consumes a lot of reference signal resources. At the same time, the UE needs to use all receive beams (Rx beams) to measure the CSI-RS and / or SSB sent on all Tx beams separately, which results in a large measurement overhead. To address these issues, artificial intelligence (AI) or machine learning (ML) technology has been proposed. Based on the measurement of some beams (pairs) or historical beam (pair) measurement results, the optimal beam (pair) can be predicted, thereby saving reference signal (RS) transmission resources, UE measurement overhead, and UE measurement delay.

[0162] However, as data-driven algorithms, AI or ML algorithms suffer from generalization issues and lack theoretical guarantees for their performance. To ensure the performance of AI or ML applications in communication systems, model monitoring of the AI ​​or ML models is necessary. AI models can be deployed on either the base station or the user equipment (UE). If the model is deployed on the base station, model monitoring is generally performed by the base station. During the model monitoring process, the base station configures a reference signal for the UE, and the UE feeds back measurement results to the base station. The base station then calculates model monitoring indicators based on the model inference results and the information fed back by the UE to determine the suitability of the current model. The specific feedback provided by the UE during the model monitoring process is related to the model monitoring indicators.

[0163] Specifically, the current air interface AI project uses the following two sub-use cases as sub-use cases for AI beam management:

[0164] BM-case (beam management case) 1: Spatial beam prediction, that is, predicting the top-K (i.e., the first K) beams (pairs) in beam set SetA based on beam set SetB measured at a certain moment;

[0165] BM-case2: Time-domain beam prediction, that is, predicting the top-K beams (pairs) of the beam set SetA at the next N' moments based on the beam set SetB measured at the past N moments.

[0166] The downlink beams in SetB are used for beam measurement, and the measurement results are used as input for the AI ​​or ML model. The output of the AI ​​or ML model can be the predicted identifiers (IDs) of the Top-K beams (pairs) of SetA or the predicted Reference Signal Received Power (RSRP) of the beams (pairs) of SetA. Based on the latter, the base station or UE can select the Top-K beam pairs according to the predicted RSRP. (The execution of this selection depends on whether the model is deployed on the base station or the UE, and can be considered post-processing.) In BM-case2, SetB can be equal to SetA or not. When SetB is equal to SetA, BM-case2 uses pure time-domain beam prediction; when SetB is not equal to SetA, BM-case2 uses both spatial and time-domain beam prediction.

[0167] In addition, currently supported model monitoring indicators include beam prediction-related indicators, the difference between measured RSRP and predicted RSRP, etc. Among them, the "difference between measured RSRP and predicted RSRP" indicator is applicable when the output of the AI ​​or ML model is the predicted RSRP of the beam (pair) of SetA.

[0168] Among them, beam prediction related indicators include Top-K / 1 beam prediction accuracy, Top-1 / K beam prediction accuracy, and optimal beam prediction accuracy within the XdB range. Specifically, the definitions of each indicator are as follows:

[0169] Top-K / 1 beam prediction accuracy: the probability that the predicted Top-K beam includes the actual Top-1 beam;

[0170] Top-1 / K beam prediction accuracy: the probability that the predicted Top-1 beam belongs to the actual Top-K beam;

[0171] X dB range optimal beam prediction accuracy: The probability that the difference between the predicted L1 (layer 1)-RSRP measurement value of the top-1 beam and the actual L1-RSRP measurement value of the top-1 beam is within X dB.

[0172] The difference between the measured RSRP and the predicted RSRP refers to the difference between the measured RSRP and the predicted RSRP of certain beams (such as the beam of Set B or the Top-K beam output by the model).

[0173] Specifically, if the "optimal beam prediction accuracy within the XdB range" is used as a model monitoring indicator, it is necessary to calculate the difference between the actual L1-RSRP of the Top-1 beam predicted by the AI ​​or ML model and the actual L1-RSRP of the actual Top-1 beam (that is, the beam with the largest actual L1-RSRP measurement value in SetA). The UE can report the measured value of the L1-RSRP of the Top-1 beam predicted by the model and the measured value of the L1-RSRP of the actual Top-1 beam to the base station. Regarding reporting, one implementation method (method 1) is that the UE feeds back the L1-RSRP measurement results of all beams of SetB and SetA to the base station, and the base station performs model inference based on the L1-RSRP of SetB, and selects the measured value of the predicted L1-RSRP of the Top-1 beam (that is, the actual L1-RSRP) and the measured value of the L1-RSRP of the actual Top-1 beam in SetA from the measurement results of SetA based on the inference result for calculation. This method requires the UE to feedback the L1-RSRP measurement values ​​of all beams in SetA, which results in a large feedback overhead. Another implementation method (method 2) is that the UE only feeds back the L1-RSRP measurement value of the Top-1 beam predicted by the model and the actual L1-RSRP measurement value of the Top-1 beam, or the difference between the two (i.e., the L1-RSRP measurement value of the Top-1 beam predicted by the model and the actual L1-RSRP measurement value of the Top-1 beam). This method requires the UE to first feed back the measurement results of SetB for model inference, and then feed back the measurement quantity used to calculate the model monitoring indicator based on the inference results of the base station. For the above-mentioned method 2, taking the BM-Case1 spatial domain beam prediction as an example, the base station side model monitoring process can be shown in Figure 2; wherein:

[0174] If the difference between the predicted L1-RSRP for the Top-K beams output by the model and the measured L1-RSRP is used as a model monitoring indicator, the UE can report the measured L1-RSRP value of the Top-K beams predicted by the model to the base station. The base station calculates the difference between the two values ​​based on the predicted L1-RSRP value of the Top-K beams output by the model. The UE's measurement of the Top-K beams can be completed in step 1: the UE measures the entire SetA beam; after the base station completes model inference, it notifies the UE of the inference results; the UE selects the L1-RSRP corresponding to the Top-K beam predicted by the model from the SetA measurement results and provides feedback.

[0175] Taking BM-Case 1 spatial beam prediction as an example, the base station-side model monitoring process can also be shown in Figure 3. The main difference from Figure 2 is that if the difference between the predicted and measured L1-RSRP of the Top-K beams is used as the model monitoring metric, as shown in Figure 3, the UE does not need to measure the SetA beam (i.e., the beams in SetA).

[0176] As described above, if the model monitoring process in Figure 2 is used, the first step is for the base station to send reference signals for both SetB and SetA. If SetB is a subset of SetA, only the reference signal for SetA needs to be sent. The second step is for the UE to provide feedback on the reference signal measurement results for SetB, and the base station performs model inference based on these results. The third step is for the base station to provide the UE with the model prediction results (such as the predicted top-1 beam) after model inference. The fourth step is for the UE to provide feedback on the L1-RSRP of the actual optimal beam and the predicted top-1 beam, or the difference between the two. The actual optimal beam is obtained by measuring the reference signal for SetA in step 1.

[0177] In order to implement the above process, steps 1 and 2 can be performed based on the current CSI feedback architecture, but configuration is required: the UE only feeds back the measurement results of SetB when feeding back in step 2. How to implement steps 3 and 4: the base station informs the UE of the inference results of the network side model, and the UE feeds back based on the inference results needs to be designed. If steps 3 and 4 are completed through the current non-periodic CSI reporting, the UE will measure the non-periodic reference signal after the downlink control information (DCI) is triggered, and then report the measurement results of the non-periodic reference signal. This process will cause unnecessary non-periodic reference signal transmission and / or measurement. Similarly, in the model monitoring process of Figure 3, steps 3 and 4 are similar to steps 3 and 4 of Figure 2, except that the feedback amount may be different, so the same problem exists. In this regard:

[0178] It is possible to complete steps 3 and 4 in Figures 2 and 3 by triggering an aperiodic CSI report. Currently, aperiodic CSI feedback is triggered by the CSI request field in the uplink DCI. The CSI request field indicates a trigger state (TriggerState). Radio Resource Control (RRC) signaling establishes an association between each trigger state and one or more aperiodic CSI reports. When the DCI triggers a trigger state, the aperiodic CSI report associated with the trigger state is triggered. If the aperiodic CSI report is associated with an aperiodic reference signal, and the aperiodic reference signal is sent after the trigger signaling, the measurement resource can be a reference signal set.

[0179] As described above, currently, if aperiodic CSI reporting is associated with an aperiodic reference signal, the UE will always measure the aperiodic reference signal after DCI triggering and then report the measurement result of the aperiodic reference signal, which may result in unnecessary aperiodic reference signal transmission and / or measurement.

[0180] Based on the foregoing, embodiments of the present disclosure provide an information transmission method, apparatus, and device to address the problem of inflexible information transmission schemes for aperiodic CSI reporting in related technologies, resulting in wasted resources. The method, apparatus, and device are based on the same patent application. Since the principles underlying the problems solved by the method, apparatus, and device are similar, their implementations can refer to each other, and any repetitions will not be repeated.

[0181] The information transmission method provided in the embodiment of the present disclosure is applied to a terminal, as shown in FIG4 , and includes:

[0182] Step 41: Determine a target reference signal according to the aperiodic channel state information (CSI) reporting trigger signaling sent by the network device;

[0183] Step 42: Determine a target measurement result corresponding to the target reference signal according to the configuration information sent by the network device;

[0184] Step 43: Send CSI to the network device based on the target measurement result; wherein the target measurement result is: a first measurement result for the target reference signal before receiving the non-periodic CSI reporting trigger signaling, or a second measurement result for the target reference signal after receiving the non-periodic CSI reporting trigger signaling.

[0185] The configuration information may directly indicate that the first measurement result is used as the target measurement result, or the second measurement result is used as the target measurement result, or may indicate relevant information capable of determining the following target reference time, but is not limited thereto.

[0186] The information transmission method provided in the embodiments of the present disclosure determines a target reference signal based on aperiodic channel state information (CSI) reporting trigger signaling sent by a network device; determines a target measurement result corresponding to the target reference signal based on configuration information sent by the network device; and transmits CSI to the network device based on the target measurement result. The target measurement result is: a first measurement result for the target reference signal before receiving the aperiodic CSI reporting trigger signaling, or a second measurement result for the target reference signal after receiving the aperiodic CSI reporting trigger signaling. The method can support enabling a UE to report measurement results (for signaling-related reference signals) before or after the aperiodic CSI reporting trigger signaling after aperiodic CSI reporting is triggered, thereby improving reporting flexibility, avoiding the UE having to perform aperiodic signal measurement for reporting after the aperiodic CSI reporting is triggered, and further avoiding resource waste caused by unnecessary transmission and / or measurement of aperiodic reference signals. This effectively solves the problem of insufficient flexibility in information transmission schemes for aperiodic CSI reporting in related technologies, which leads to resource waste.

[0187] The target reference signal corresponds to an inference result obtained by the network device according to an artificial intelligence AI or machine learning ML model.

[0188] This can support better model monitoring of network devices.

[0189] In an embodiment of the present disclosure, determining the target measurement result corresponding to the target reference signal according to the configuration information sent by the network device includes: determining, according to the configuration information sent by the network device, to use the first measurement result as the target measurement result corresponding to the target reference signal under a first condition, and determining to use the second measurement result as the target measurement result corresponding to the target reference signal under a second condition; wherein the first condition includes at least one of the following: the target reference signal is not received within a time period between the moment when the non-periodic CSI reporting trigger signaling is received and the target reference time; the configuration information configures the CSI reporting to be a reference signal before the non-periodic CSI reporting trigger signaling; wherein the second condition includes at least one of the following: the target reference signal is received within a time period between the moment when the non-periodic CSI reporting trigger signaling is received and the target reference time; the configuration information configures the CSI reporting to be a reference signal after the non-periodic CSI reporting trigger signaling.

[0190] In this way, the first measurement result or the second measurement result can be accurately supported and reported. The target reference signal can be understood as a reference signal associated with or indicated by the aperiodic CSI reporting, but is not limited thereto.

[0191] The target reference time is the time when the CSI is reported or the time when a predefined signal is received.

[0192] This allows the target reference time to be clearly defined. The predefined signal can be a signal defined by the network device that serves as a reference. If a target reference signal is transmitted between the time the CSI reporting trigger signal is received and before the time the target reference signal is received, the UE can report the measurement results of the target reference signal. Otherwise, the UE can report the measurement results of the target reference signal before the trigger signal is received, but this is not limited to the case.

[0193] In an embodiment of the present disclosure, determining the target reference signal based on the non-periodic channel state information CSI reporting trigger signaling sent by the network device includes: determining the target reference signal based on the non-periodic channel state information CSI reporting trigger signaling and first indication information sent by the network device; wherein the first indication information is used to instruct the terminal to measure or report the measurement results of part of the reference signal associated with the non-periodic CSI reporting trigger signaling.

[0194] This can support the terminal to report the measurement results of some reference signals, further reducing resource consumption.

[0195] The first indication information is carried in the aperiodic CSI reporting trigger signaling, or carried in downlink control information DCI that carries the aperiodic CSI reporting trigger signaling.

[0196] This can support the implementation of carrying the first indication information in multiple ways.

[0197] In an embodiment of the present disclosure, the CSI sent to the network device includes at least one of the following: the layer 1 reference signal received power L1-RSRP of the target reference signal; information of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located; the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located; and second indication information, wherein the second indication information is used to indicate whether the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located is within a preset range.

[0198] This can support the network device to perform model monitoring in multiple ways. The target reference signal information may include L1-RSRP and / or index information of the target reference signal, which is not limited here.

[0199] The present disclosure also provides an information transmission method, which is applied to a network device, as shown in FIG5 , and includes:

[0200] Step 51: Send aperiodic channel state information (CSI) reporting trigger signaling and configuration information to the terminal;

[0201] Step 52: Receive the CSI sent by the terminal according to the aperiodic CSI reporting trigger signaling and configuration information; wherein the aperiodic CSI reporting trigger signaling is used by the terminal to determine a target reference signal, and the configuration information is used by the terminal to determine a target measurement result corresponding to the target reference signal; the target measurement result is: a first measurement result for the target reference signal before receiving the aperiodic CSI reporting trigger signaling, or a second measurement result for the target reference signal after receiving the aperiodic CSI reporting trigger signaling.

[0202] The configuration information may directly indicate that the first measurement result is used as the target measurement result, or the second measurement result is used as the target measurement result, or may indicate relevant information capable of determining the following target reference time, but is not limited thereto.

[0203] The information transmission method provided in the embodiments of the present disclosure comprises: sending aperiodic channel state information (CSI) reporting trigger signaling and configuration information to a terminal; and receiving CSI sent by the terminal in accordance with the aperiodic CSI reporting trigger signaling and configuration information; wherein the aperiodic CSI reporting trigger signaling is used by the terminal to determine a target reference signal, and the configuration information is used by the terminal to determine a target measurement result corresponding to the target reference signal; the target measurement result is: a first measurement result for the target reference signal before receiving the aperiodic CSI reporting trigger signaling, or a second measurement result for the target reference signal after receiving the aperiodic CSI reporting trigger signaling; and can support enabling the UE to report measurement results (for signaling-related reference signals) before or after the aperiodic CSI reporting trigger signaling after aperiodic CSI reporting is triggered, thereby improving reporting flexibility, avoiding the UE having to perform signal measurement after the aperiodic CSI reporting is triggered, and further avoiding resource waste caused by unnecessary transmission and / or measurement of aperiodic reference signals. This effectively solves the problem of insufficient flexibility in information transmission schemes for aperiodic CSI reporting in related technologies, which leads to resource waste. The sending to the terminal here simply means that the network device sends the relevant information in the form of a wireless signal, and the target recipient is the terminal. The terminal obtains the relevant information by receiving the wireless signal.

[0204] The target reference signal corresponds to an inference result obtained by the network device according to an artificial intelligence AI or machine learning ML model.

[0205] This can support better model monitoring of network devices.

[0206] Furthermore, the information transmission method also includes: obtaining a monitoring data set based on the inference result and the target measurement result corresponding to the inference result; obtaining model monitoring indicator data based on the monitoring data set; and determining whether the AI ​​or ML model on the network device side meets the usage conditions based on the model monitoring indicator data.

[0207] This allows for complete monitoring of the model. "Whether the conditions for use are met" can also be referred to as "whether it is applicable" or "whether it still works," which is not limited here.

[0208] Among them, sending non-periodic CSI reporting trigger signaling to the terminal includes: sending non-periodic CSI reporting trigger signaling and first indication information to the terminal; wherein, the first indication information is used to instruct the terminal to measure or report the measurement results of part of the reference signal associated with the non-periodic CSI reporting trigger signaling.

[0209] This can support the terminal to report the measurement results of some reference signals, further reducing resource consumption.

[0210] In the embodiment of the present disclosure, the first indication information is carried in the aperiodic CSI reporting trigger signaling, or carried in downlink control information DCI that carries the aperiodic CSI reporting trigger signaling.

[0211] This can support the implementation of carrying the first indication information in multiple ways.

[0212] The CSI sent by the terminal includes at least one of the following: the layer 1 reference signal received power L1-RSRP of the target reference signal; the information of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located; the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located; and second indication information, wherein the second indication information is used to indicate whether the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located is within a preset range.

[0213] This can support the network device to perform model monitoring in multiple ways. The target reference signal information may include L1-RSRP and / or index information of the target reference signal, which is not limited here.

[0214] The information transmission method provided in the embodiment of the present disclosure is described below with an example of a base station as an example of a network device.

[0215] To address the above technical issues, the embodiments of the present disclosure provide an information transmission method, which can be specifically implemented as a CSI reporting method. After the base station completes AI model inference, it triggers the UE to report information to the base station based on the inference results, thereby realizing model monitoring on the base station side. This solution mainly includes the following contents:

[0216] Part 1. The base station configures the measurement resources associated with CSI reporting. After completing model inference (based on the inference results), the base station triggers aperiodic CSI reporting (corresponding to the above-mentioned sending of aperiodic channel state information CSI reporting trigger signaling and configuration information to the terminal):

[0217] a) If no reference signal associated with the aperiodic CSI reporting (corresponding to the target reference signal) is sent between the time after the aperiodic CSI reporting trigger signaling and the aperiodic CSI reporting time (corresponding to the time of the CSI reporting) (or before a defined reference time (such as the time of receiving the predefined signal)) (corresponding to the above-mentioned failure to receive the target reference signal in the time period between the time of receiving the aperiodic CSI reporting trigger signaling and the target reference time), or the base station configures CSI reporting to be based on the reference signal before the trigger signaling (corresponding to the above-mentioned configuration information configuring CSI reporting to be based on the reference signal before the aperiodic CSI reporting trigger signaling), the UE provides feedback based on a measurement result of the reference signal associated with the (aperiodic) CSI reporting before the trigger signaling (corresponding to the above-mentioned determination, according to the configuration information sent by the network device, under a first condition, to use the first measurement result as the target measurement result corresponding to the target reference signal; and sending CSI to the network device based on the target measurement result), the measurement result being previously stored by the UE (i.e., pre-stored);

[0218] b) If a reference signal associated with the aperiodic CSI reporting is sent between the time when the aperiodic CSI reporting trigger signaling is received and the time when the aperiodic CSI reporting is triggered (or before a defined reference time) (corresponding to the above-mentioned reception of the target reference signal within the time period between the time when the aperiodic CSI reporting trigger signaling is received and the target reference time), or the base station configures the CSI reporting to be based on the reference signal after the trigger signaling (corresponding to the above-mentioned configuration information configuring the CSI reporting to be based on the reference signal after the aperiodic CSI reporting trigger signaling), the UE provides feedback based on the measurement result of the reference signal associated with the (aperiodic) CSI reporting after the trigger signaling (corresponding to the above-mentioned determination, according to the configuration information sent by the network device, under the second condition, to use the second measurement result as the target measurement result corresponding to the target reference signal; and sending CSI to the network device based on the target measurement result);

[0219] This section primarily addresses the need for the UE to determine whether to report CSI based on the measurement results of the reference signal before the CSI reporting trigger signaling (corresponding to the first measurement result described above) or the measurement results of the reference signal after the trigger signaling (corresponding to the second measurement result described above). In other words, it specifies that the UE stores the measurement results and determines whether the measurement results to be fed back are the measurement results of the reference signal before the trigger signaling or the measurement results of the reference signal after the trigger signaling.

[0220] In addition, considering that model monitoring is essentially a comparison of the performance of the AI ​​algorithm and the performance of a benchmark result at the same time point, the sending of the reference signal and the reporting of the UE need to ensure the so-called "same time point", that is, to clarify which reference signal or signals the UE measures. Specifically, the UE measurement time can be specified through the definition of the CSI reference resource, but it is not limited to this.

[0221] Part 2. Optionally, the base station may instruct the UE to measure or report only part of the reference signals associated with the triggered CSI reporting (corresponding to the Top-K beams output by the model) (that is, the measurement object can be "indicated"), corresponding to the above-mentioned sending of non-periodic CSI reporting trigger signaling and first indication information to the terminal; wherein, the first indication information is used to instruct the terminal to measure or report the measurement results of part of the reference signals associated with the non-periodic CSI reporting trigger signaling. Specifically, the indication information can be configured in the trigger state of the non-periodic CSI (corresponding to the above-mentioned first indication information being carried in the non-periodic CSI reporting trigger signaling) or carried by the DCI that triggers the non-periodic CSI reporting (corresponding to the above-mentioned first indication information being carried in the downlink control information DCI that carries the non-periodic CSI reporting trigger signaling); specifically, the indication information can be implemented in at least one of the following ways:

[0222] For implementation a), the indication information may be represented as a bitmap, where the bitmap length is equal to the number of reference signals in the reference signal set associated with the (aperiodic) CSI reporting. For example, a bit "1" indicates that the UE measures the corresponding reference signal, while a bit "0" indicates that the UE does not measure the corresponding reference signal.

[0223] In implementation b), the indication information may be represented as N bits, where the decimal value corresponding to the N bits represents the 2 values ​​associated with the UE measurement and (non-periodic) CSI reporting. N If the CSI report is associated with 8 reference signals, a 3-bit indication can be used, where 000 represents the first reference signal, 001 represents the second reference signal, and so on.

[0224] In implementation method c), the indication information may be represented as (at least one) integer value in the range of 1 to M, where M is the number of reference signals associated with the (non-periodic) CSI report. The integer value i represents that the UE needs to measure the i-th reference signal. Specifically, the indication information may be a plurality of integer values ​​used to instruct the UE to measure multiple reference signals. The method of implementation method b) can only indicate one reference signal using N bits. Generally, the indication method of implementation method b) can be used in L1 signaling (such as DCI) indications, and implementation method c) can generally be used in RRC signaling indications.

[0225] This section mainly involves: the UE only measures or reports the measurement results of some reference signals associated with non-periodic CSI reporting; it can be understood as indicating that: based on Part 1, the UE determines whether the feedback measurement result is a reference signal before or after the trigger signaling, and on this basis, only feeds back a subset of the reference signals associated with the trigger signaling.

[0226] Part 3. The UE feeds back the measurement results (corresponding to sending CSI to the network device based on the target measurement results) based on the trigger information (which may include the above-mentioned CSI reporting trigger signaling and configuration information). The specific feedback content may be configured by the base station and may be one of the following:

[0227] a) the L1-RSRP of the reference signal associated with or indicated by the triggered CSI reporting (corresponding to the layer 1 reference signal received power L1-RSRP of the target reference signal);

[0228] b) The reference signal associated with or indicated by the triggered CSI report and the maximum L1-RSRP of the reference signals in the set to which the reference signal belongs (corresponding to the L1-RSRP of the top-1 beam predicted by the model and the actual top-1 beam in SetA), corresponding to the information of the above-mentioned target reference signal and the maximum L1-RSRP of the reference signals in the set to which the target reference signal belongs;

[0229] c) the difference between the L1-RSRP of the reference signal associated with or indicated by the triggered CSI reporting and the maximum L1-RSRP of the reference signals in the set to which the reference signal belongs (corresponding to the difference between the L1-RSRP of the top-1 beam predicted by the model and the actual top-1 beam in SetA), corresponding to the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signals in the set to which the target reference signal belongs;

[0230] d) Indicates whether the difference between the L1-RSRP of the reference signal associated with or indicated by the triggered CSI report and the maximum L1-RSRP of the reference signals in the set to which the reference signal belongs is within the XdB range (corresponding to the above-mentioned second indication information, the second indication information is used to indicate whether the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signals in the set to which the target reference signal belongs is within a preset range), where X may be specified by the protocol or configured by the base station; the feedback information may be "1" or "0", such as "1" represents that it is within the XdB range, and "0" represents that it is not within the XdB range.

[0231] As mentioned above, part 3 indicates which measurement results of the measurement objects are fed back by the UE.

[0232] The following is a specific example to illustrate this solution.

[0233] Example 1:

[0234] In this embodiment, it is assumed that an AI or ML model is deployed on the base station side for spatial prediction, that is, the optimal beam in SetA is predicted based on the measurement results of SetB beams (i.e., beams in SetB). The input of the AI ​​or ML model is the L1-RSRP of SetB beams, and the output is the ID of the predicted optimal beam in SetA. Assume that, as shown in Figure 6, SetA includes 32 transmit beams, SetB includes 8 transmit beams (beam #1, beam #5, beam #9, beam #13, beam #17, beam #21, beam #25, beam #29), and SetB is a subset of SetA.

[0235] Specifically, it is assumed that the model monitoring indicator is the optimal beam prediction accuracy within a 1dB range. The base station configures CSI reporting #1 and CSI reporting #2 (including configuring the reporting type (periodic or non-periodic), and may also include a trigger status (which may indicate the reference signal to be measured and reported)). Among them, CSI reporting #1 is a periodic CSI reporting, and the associated measurement resources are the 32 reference signals corresponding to the SetA beam. The base station may instruct the UE to report the measurement results of part of the SetA reference signals in CSI reporting #1. Part of the SetA reference signals corresponds to the 8 reference signals of SetB. CSI reporting #2 is a non-periodic CSI reporting, and the associated measurement resources are the 32 reference signals corresponding to the SetA beam. Configure aperiodic CSI reporting trigger states #1 to #24. Each of these trigger states is associated with aperiodic CSI reporting #2. However, the indication information for each trigger state contains different integer values. The integer value i represents the UE's measurement or reporting result for the i-th reference signal among the 32 reference signals corresponding to beam SetA. CSI reporting #2 reports the L1-RSRP of the i-th reference signal and the maximum L1-RSRP of the reference signals in the same set as the i-th reference signal.

[0236] Specifically, as shown in Figure 7, based on the base station configuration information, the UE measures the reference signal of SetA at T0, reports the L1-RSRP of SetB at T1 (performing CSI reporting #1), and stores the measurement results of the reference signals in SetA. After receiving the L1-RSRP reported by the UE, the base station performs model inference, and the model inference result is: Beam #3 in SetA is the optimal beam. At time T2, the base station triggers aperiodic CSI trigger state #5 (i.e., triggers aperiodic CSI reporting) through DCI signaling, corresponding to aperiodic CSI reporting #2, and the reporting time is T3. Corresponding to the model inference result, the indication information of trigger state #5 (corresponding to the first indication information mentioned above) is the integer value 3 (i.e., indicating that the measurement result of the reference signal of beam #3 is reported); the corresponding target reference signal corresponds to the inference result obtained by the network device based on the artificial intelligence AI or machine learning ML model. Between T2 and T3, assuming that no reference signals in SetA are transmitted, the UE performs CSI reporting #2 at time T3 based on the measurement of SetA at time T0. The UE's reporting content is the L1-RSRP of the third reference signal in SetA at time T0 (i.e., the reference signal corresponding to beam #3) and the maximum L1-RSRP in SetA at time T0 (corresponding to the above-mentioned failure to receive the target reference signal in the time period between the time of receiving the non-periodic CSI report trigger signaling and the target reference time; the first measurement result is used as the target measurement result corresponding to the target reference signal). After receiving the UE's CSI report #2, the base station can calculate whether the difference between the L1-RSRP of the optimal beam predicted by the model and the actual optimal beam is within 1dB (corresponding to the above-mentioned acquisition of model monitoring indicator data; based on the model monitoring indicator data, determining whether the AI ​​or ML model on the network device side meets the usage conditions).

[0237] Example 2:

[0238] In this embodiment, it is assumed that an AI or ML model is deployed on the base station side for spatial prediction. The input of the AI ​​or ML model is the L1-RSRP of the SetB beam, and the output is the predicted L1-RSRP of all beams in SetA. The beam configuration on the base station side can be shown in Figure 6. Specifically, it is assumed that the model monitoring indicator is the difference between the predicted L1-RSRP and the measured L1-RSRP of the top-3 beams output by the model. The base station configures CSI reporting #1 and CSI reporting #2. Among them, CSI reporting #1 is periodic CSI reporting, and the associated measurement resources are the 8 reference signals corresponding to the SetB beam. CSI reporting #2 is aperiodic CSI reporting, and the associated measurement resources are the 32 reference signals corresponding to the SetA beam. Configure aperiodic CSI reporting trigger states #1 to #10. Each of these trigger states is associated with aperiodic CSI reporting #2. However, the bitmap information in the indication information (corresponding to the first indication information) for each trigger state is different, and the bitmap length can be 32 bits. The report content corresponding to CSI reporting #2 is the L1-RSRP of the reference signal corresponding to the bitmap information "1."

[0239] As shown in Figure 8, based on the base station configuration information, the UE measures Set B's reference signal at T0 and reports Set B's L1-RSRP at T1 (performing CSI reporting #1). After receiving the L1-RSRP reported by the UE, the base station performs model inference, which results in: Beams #3, #12, and #20 in Set A are the top-3 beams. At T2, the base station triggers aperiodic CSI trigger state #2 (i.e., triggers aperiodic CSI reporting) through DCI signaling. This corresponds to aperiodic CSI reporting #2, and the CSI reporting time is T4. Corresponding to the model inference result, the bitmap indication information of trigger state #2 is [00100000000100000001000000000000], indicating that the UE measures and reports the L1-RSRP of the 3rd, 12th, and 20th reference signals in the SetA reference signal associated with the non-periodic CSI report #2; corresponding to the above-mentioned target reference signal and the inference result obtained by the network device according to the artificial intelligence AI or machine learning ML model. At time T3, the base station sends the 3rd, 12th, and 20th reference signals, and the UE performs CSI reporting #2 at time T4 based on the measurement result at time T3. The reporting content of the UE corresponds to the L1-RSRP of the 3rd, 12th, and 20th beams in SetA (corresponding to the above-mentioned target reference signal received in the time period between the moment of receiving the non-periodic CSI report trigger signaling and the target reference moment; the second measurement result is used as the target measurement result corresponding to the target reference signal). After receiving CSI report #2 from the UE, the base station can calculate the difference between the predicted L1-RSRP value of the top-3 beams predicted by the AI ​​model and the measured L1-RSRP value of the predicted top-3 beams.

[0240] From the above, the solution of this embodiment 2 can implement model monitoring based on the difference between the predicted L1-RSRP value and the L1-RSRP measurement value of the Top-K (K=3) beams, avoid sending SetA reference signals, and reduce RS overhead.

[0241] In addition, in this scheme, for this embodiment 2, it can also be implemented as follows: the base station sends the reference signal of Set A at time T0, and indicates the bitmap of trigger state #2 at time T2, and no longer performs the above-mentioned operation at time T3; the UE feeds back the corresponding measurement result in Set A at time T0 according to the bitmap indicated at time T2 at T4, but is not limited to this.

[0242] It is noted here that the relevant contents of each example can be referenced across each other, and the repeated parts will not be repeated.

[0243] From the above, the base station side in the solution provided by the embodiment of the present disclosure involves the following contents: the base station triggers non-periodic CSI reporting based on the inference results of the AI ​​or ML model, which is used to calculate the model monitoring index (using the results reported by the UE). Specifically: the base station can record the inference results of each AI or ML model and the measurement results corresponding to the model inference fed back by the UE (corresponding to the above-mentioned monitoring data set obtained based on the inference results and the target measurement results corresponding to the inference results); the base station calculates the average model monitoring index based on the statistics of multiple results (corresponding to the above-mentioned acquisition of model monitoring index data based on the monitoring data set), so as to determine whether the AI ​​or ML model on the base station side can still work (corresponding to the above-mentioned determination of whether the AI ​​or ML model on the network device side meets the usage conditions based on the model monitoring index data). Among them, the measurement of the reference signal associated with the non-periodic CSI reporting can be before or after the trigger signaling, and can be the measurement of part of the associated reference signal. Correspondingly, the UE side in the solution provided by the embodiment of the present disclosure involves the following contents:

[0244] 1) The UE reports CSI according to the configuration information of the base station, and determines whether the reported information is based on the measurement results of the reference signal before the CSI report trigger signaling or the measurement results of the reference signal after the trigger signaling, and the measurement results are pre-stored by the UE; that is, the UE needs to store the measurement results before the trigger signaling, and determine, based on the trigger signaling, whether the feedback measurement results are before or after the trigger signaling.

[0245] 2) According to the instruction information of the base station, the UE can only measure or report the measurement results of some reference signals associated with the CSI reporting;

[0246] 3) The feedback content of the UE can be configured by the base station. For the specific feedback content, please refer to the above part 3 and will not be repeated here.

[0247] Based on the above, in this solution, it can be: DCI trigger result feedback, the feedback reference signal measurement is not necessarily sent after the trigger signaling (that is, DCI is only the trigger result feedback, the UE does not necessarily continue to measure the reference signal after receiving the DCI, the UE feedback can be the measurement result of step 1 in Figure 2 or Figure 3), correspondingly, the non-periodic reference signal can be sent before or after the trigger.

[0248] In summary, this solution solves the problem of how the UE reports information for model monitoring to avoid resource waste when the base station side performs model training and model inference. Specifically, the embodiment of the present disclosure adopts a solution of non-periodic reporting after the base station completes model inference: the base station triggers the UE to report information for model monitoring based on the inference result, and the result reported by the UE can be based on the measurement before the trigger signaling or the measurement after the trigger signaling. In addition, the base station can instruct the UE to measure or report part of the measurement resources associated with the CSI report based on the inference result, so that the UE reports the L1-RSRP measurement value of the beam predicted by the model, thereby assisting the base station in calculating the model monitoring indicator and saving resources. The embodiment of the present disclosure can implement a solution for AI model performance monitoring on the base station side and improve the performance of AI models applied to communication networks.
